I’ll revive this older thread to plug my HbrewO system after all these years. It consistently puts out 0 TDS and 0 chlorine water from my crappy tap water. Recently it took a hit when I left it outside full of water in freezing temps, and the flow restrictor cracked. Water gushed out instead of being forced through the filter cartridges and RO membrane. I contacted HbrewO and Mike is sending me a new flow restrictor. Because I needed to make some water, I had also ordered these flow restrictors from Amazon which are rated with the same output rate as the original. They seem to work perfectly with the minor addition of a new piece of 1/4” OD polyethylene tubing to make the connection.

The first pic is the original part, the second pic shows the installed replacement. (The “replace 8.26.23” on a cartridge is for reference only, that cartridge is still below its rated water capacity.)
